Lower Limb Venous Insufficiency and the Effect of Radiofrequency Treatment Versus Open Surgery
May 10, 2023 updated by: Oskar Nelzén, University Hospital, Linkoeping
Lower Limb Venous Insufficiency and the Effect of Radiofrequency Treatment Versus Open Surgery. A 5-year Follow-up Using Duplex Ultrasound, Plethysmography, VCSS, AVVQ and EQ-5D
200 patients with insufficient great saphenous veins will be randomized to either radiofrequency ablation or high ligation/stripping (open surgery).
They will be examined according to standardized examination protocol Venous Clinical Severity Score (VCSS), with duplex ultrasound and plethysmography pre- and postoperatively (1-month, 1-, 3 and 5 years).
They are to fill questionnaires EuroQol 5 Dimensions (EQ-5D) and disease specific Aberdeen Varicose Vein Questionnaire (AVVQ).
